reboot/shutdown phase

Hello,
I have my workflow on Debian/Sid, with kernel compiled by https://www.kernel.org/, currently at version 5.14.1, on asus x555ln notebook.

The problem occurs when the external USB 3 harddisk is disconnected from itself: in some cases it is no longer reconnected and if I try to do "sync" from console, this command appears freezed.

If I reboot, at the end the system log shows that it has reached the "Rebooting" phase but remains in loops on the message indicated above (see image file).

When this happens, the system should recognize that the harddisk is no longer available or stalled, to interrupt the write of the cache and terminate the reboot or shutdown phase.

Thanks,
Antonio
